PUMP.

l SPECIFICATION forming part of Letters Patent No. 597,155, dated January 11, 1898.

Application flied December 17, 1896. Serial No. 616,033. (No model.)

To all whom it may concern:

Be it known that l, Moi-mis D. TEMPLE, a citizen of the United States, and a resident of the city of Chicago, Cook county, Illinois, have invented certain 'new and useful Improvements in Pumps, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this speciiication.

The present invention has relation more particularly to that class of pumps designed not only to raise Water from the well or cistern, but also to force air beneath the surface of the Water in order to destroy the animalculte, organic matter, or like disease-germsA contained therein. An example of this type of pump is illustrated in Letters Patent No. @0,776, granted to me January 3l, 1893.

The invention has for its object, primarily, to provide for a more effective delivery of the air into the Well or cistern, so that the air thus delivered from the pump shall pass upward to the surface of the Well or cistern and shall not be returned directly into the pump.

The invention has also for its object to improve the pump in various particulars, all of which will be hereinafter described, and set forth in the claims at the end of this speciiication.

Figure l is a view in central vertical section through a pump embodying my invention. Fig. 2 is a view in side elevation through the lower portion of the pump. Fig. 3 is a view in horizontal section on line 3 3 of Fig. l. Fig. e is a detail view, in side elevation, of the guide or delector. Fig. 5 is a view in central vertical section through a modified form of the invention.

A designates the cylinder of the pump, within which cylinder is the piston B, that is carried by the piston-rod B. The piston B is shown as consisting of reversely-arranged cup-leathers held between screw-threaded clamping-plates, but this particular construction of piston is not essential. The upper part of the cylinder A forms what may be termed the Water-cylinder, While the lower part of the cylinder A forms an air-cylinder. The upper end of the cylinder A is screw- .threaded and engages an interiorly-extending screw-threaded iiange at the top of an outer casing C, that encircles the cylinder A throughout more or less of its length. The space between the cylinder A and casing C serves for the passage of Water from the well,

kand the flange c at the top of the casing C is provided with perforations or slots c, through which the Water will pass upwardly from the Well or cistern, the slots or perforations c being closed against the backiow of Water by means of an annular valve D, that rests upon the top of the flange c. The upper end of the casing C is also screw-threaded exteriorly to engage with an interior thread e, formed at the base of the cap E, and the top of this cap E is provided With a screw-threaded annular ange e', With which engages the correspondingly-threaded lower end of the supplemental cap F. The exterior of the cap E and the eX- terior of the upper or lower part of the supplemental cap F may be of polygonal shape to permit these parts to be more readily connected together by means of a suitable Wrench, although I do not regard this feature as in any respect essential and have not therefore deemed it necessary to illustrate the same in the drawings.

The cap E is formed with the transverse diaphragm e2, having ports eS therethrough, above which rests the valve-leather G, by which the ports es Will be closed against backloW of Water from the tube K. Preferably the valve G, which may be of leather, rubber, or like flexible material, is heldin place by a bushing H, the reduced threaded lower end of which engages with a correspondingly-threaded hole formed in the center of the diaphragm e2, and by preference the upper part of the bushing H is chambered to form a stuiiingbox and to receive the thread ed cap h, through Which bushing and cap the piston rod B passes. The upper end of the supplemental cap F Will be threaded in usual manner to receive the lower end of the pump-tube K.

From the construction of parts as thus far defined it will be seen that as the pump-piston B descends Water will be drawn up through the annular space between the cylinder A and the casing C and, lifting the valve D, will pass upward through the ports c' and into the cylinder A. lVhen the stroke of the piston B is reversed, the valve D will close and .thus prevent the baclriiow of the Water from IOO the cylinder, while the valve G will open to allow the water to pass into the pump-tube.

The lower end of the cylinder A is exte riorly threaded to engage a correspondinglythreaded upright annular iiauge formed on the base M, that closes the `lower end of the cylinder A. The base M in the embodiment ot' my invention shown in Fig. l is provided with a lateral extension M', through which leads a port m, that connectsthe interior of f the cylinder A with an air-supply pipe N;

that leads from above the well and is attached to the arm or -extension M. Above the port m and resting upon the bottom of the casing M is an annular valve P, preferably of leather, rubber, or the like, the edge of this valve being clamped between thelower end of the cylinder A and the base M. The valve P will raise and uncoverport mon the upstroke of the piston B, but will descend and close the port m on the downward stroke of the piston. Into the bottom of the base A is tapped a short pipe R, the lower end of which is formed with a chambered head R', from the upper face of which extends the port r. Upon the head R' and over the port r rests an annular valve r', that is held normally against its seat by a weighted ring r2, that loosely encircles the pipe R. From. the foregoing description it will be seen that at each upstrole of the piston B air will be drawn from above the surface of the well down through the pipe N and into the lower portion of the cylinder A, and as the air is thus drawn into the cylinder A the valve P will be lifted to admit the air to the interior of the cylinder, while the valve fr" will close against the port fr and thus guard against the entrance of water through the pipe R. On the downstroke of the piston B the valve P will close the port m, while the pressure of air passing through the pipe R will lift the valve r from its seat, thereby permitting the air to pass freely into the body of water within which the pump is submerged. Hence it will be seen that at each up-anddown movement of the piston water will be lifted from the Well and air will be forced thereinto.

In order to insure that the air passing from the lower end of the cylinder A shall be delivered into the water in such manner that it will rise to the surface of the well and will not pass immediately with the water entering the pump through the annular space between the cylinder A and casing C, I provide a guide or deflector that will guard against the direct passage of the air into that part of the body of water that is being drawn up into the pump. The guide or deflector which I prefer to use is that to be hereinafter described, although I Wish it distinctly understood that my invention (except where so specifically stated in the claims) is not restricted to the particular construction of deflectoror guide. Between the base M and the lower end of the casing C is interposed the defleotor S. Preferably, although not essentially, this deflector is formed raised bars or ngers s3.

as a single casting having the depending wall s and having an inwardly-extending iiange s that rests upon the upper end of the base M. The upper part of the deiiector is provided with raised plates s2 and preferably also with At opposite points in the depending walls are formed openings, (see Figs. l and 4,) through one of which openings eXtends the lateral arm M', and both of which openings serve as passage-ways for air as it is forced from the bottom of the cylinder A. By reference to Figs. l and 3 of the drawings it will be seen that the openings through the walls s of the deiiector are located immediately beneath the raised plates or walls s2 at the upper part of the deector. Consequently as the air discharging from the bottom of the cylinder A passes through the openings formed in the wall s and in upward direction the raised plates or walls s2 will prevent the air being drawn into the casing C, thus enabling it to rise directly upward into the body of water above the pump. The vertical bars or iingers S3 serve as a screen to prevent the access of chips, leaves, or the like into the body of the casingC. Preferably the guide or deflector S is strengthened by internal and ex ternal ribs s4 and S5, respectively, although these are not essential.

In the modification of the invention illustrated in Fig. `5 of the drawings the cylinder A, the piston B, the @asin g C, and the cap and supplemental cap and valves therein contained are the same in construction as hereinbefore described. In this form of the invention, however, the supply of air to the lower part of the cylinder A is admitted through a hollow piston-rod B2, and to the lower end of this piston-rod is connected a .Valve-chamber R2, similar to the pipe and chamber R andI R shown in Fig. 1 of the drawings, and upon the upper faceof the valve-chamber R2 is mounted an annular valve r4 and Weight T5, the valve r4 serving to control the ports r6, as in the construction hereinbefore described. The base M of the pump is provided with an air-discharge pipe and chamber R and R', furnished with valves fr and weights r2, as hereinbefore described. In this form of my invention the guide or deiiector S is shown closed at its bottom and provided at the side with a short guide-pipe S', leading, preferably, to a point above the lower end of the casing C.

From the foregoing description it will be seen that on the downstroke of the piston B water will be drawn into the pump, as hereinbefore described, and the air within the lower part of the cylinder A will be forced out through the pipe R into the closed deflector S and will be delivered thence by the pipe S into the body of water at a point above the induction end of the casing C. On the upstroke of the piston B the valve r' will close and the valve r4 will open, therebyadmitting air into the lower part of the cylinder A through the hollow piston-rod B2.
